Is 3-Way SLI GTX780 worth it? Skunkworks Gaming Performance

2014-10-01
what is up guys Jays two cents here and a while back I upgraded to x99 the eight core 16 thread Xtreme processor and yeah I did a video about that and you guys really seemed to like that build log now before we go any farther in this video I'm gonna go ahead and dress something yes I did pop another eye vessel thing that's why I was wearing my Gunners because I've been staring at the screen non-stop for the last two days and I didn't want to look entirely like a zombie for this video but a half a bottle of Visine and these Gunners later my eyes are still pretty effed up so no guys I don't live in Washington or Colorado therefore let's not go there when it comes to the comments but where we are going to go today's we're going to take a trip down gaming Lane with skunk work so we're going to see how well that third 780 actually scaled so back in like April or something like that I did a video about moving to SLI with my seven 80s and that was still on my z77 platform and I talked about what it was like going you know 57 60 by 1080 you know three way or three monitors and V surround SLI how it scaled it all of that now while back when I moved to the x99 platform while I was in there I went ahead and tossed in my third 780 I wanted to see how well 3-way was going to work keep it clean guys it's not not that kind of 3-way it's the the tech 3-way which is essentially just as sexy if you ask me now one of the reasons why this video is so late is because I was having some massive scaling problems with 3-way SLI in fact if I was to disable one of the GPUs I was getting the exact same performance numbers with two-way if I disabled the second GPU I was getting the exact same numbers as I was with one GPU so obviously there was a problem there so for about the last month I have been banging my head against the table quite literally in fact that's why sometimes you see marks on my face because I did a video after banging my head on the desk because I was so fed up with the machine in fact I started to hate this machine because it was turning out to be nothing but one big pile of problems if you guys want any proof of that just head on over to twitter and ask EVGA jacob how vocal I was about things were not working properly yeah things are not working properly it is making me very angry sorry for that but I was getting pretty damn fed up with the system well anyway Jacob and I actually live pretty close to each other and he happened to stop by last night and we did a lot of tests to the machine and we found the most unlikely culprit my CPU overclock was actually causing the problem the more the CPU is overclocked the worse the SLI performance was in fact the worse all GPU performance was but then we found out it actually had a correlation to do with the CPU overclock and the RAM overclocked in which order you do it in in fact it created some sort of bug in the intel algorithm where something weird was happening with the PCI Express Lanes or the PCI Express bus or something where the graphics cards were never even getting a chance to do anything it was almost like a synthetic bottleneck if you will but anyway we figured it out the system is running full tilt right now and I got to tell you now that I'm experiencing the 3-way yeah annachi tois baby aqua Townsend now let me just start by saying that this system is stupidly fast I mean it is just stupid I can't even I can't even fathom the point of having a system this powerful but I've got it so might as well flaunt it so anyway my three gtx 780 s are water-cooled they are not the TI is they're certainly not the titans in fact they are reference PCBs they're not even for the win or classified or any of those cards these are stock reference PCBs slap the water block on them custom wrote a BIOS myself slapped it on over volted it and just said balls to the wall if the cards blow up well I'll cry but for the sake of science sure I said I was going to push these cards as far as I could that's exactly what I've done now we've got a couple of tests I ran here I ran some synthetics like 3d mark 11 3d mark fire strike fire strike extreme valley heaven benchmark or valley heaven note Unigine heaven that's right Ally something else in fact valley doesn't even really work well with three-way it's one put that out there but then I ran battlefield 4 metro 33 and tomb raider and as far as titles I want to know real quickly from you guys tell me on Twitter please go over to Twitter make an account if you didn't because it's actually the easiest way to get a hold of me and tell me what titles you guys would like to see me include in these future benchmarks because Crysis 3 I don't think it's very well optimized watchdog we know it's not very well optimized I've got Borderlands and those games but they're not really that new so they're not really pushing these systems very hard so what do you guys want to see when it comes to these benchmarks if you're disappointed with the titles I chose today I'm sorry I'm working on it I will get more titles in fact if you guys have any keys feel free to toss them my way and I will include them in these benchmarks now ok let's go ahead and start with fire strike extreme now I was getting just under 17,000 getting like sixteen thousand nine hundred in three ways before fixing the issue with the CPU and whatnot so now that we're fixed my score jumped and I'm not saying I'm sterile by the way I'm not fixed like neutered the system was neutered but we've we've we went ahead and slapped his e-peen back gone and now you're getting these scores so twenty three thousand two hundred thirty nine and fire strike holy that's more like where it should be in fact when I tweeted out my scores you guys are like uh luggage a but those scores suck sounds going what do you miss to go to suck I start looking into it I'm going you're right my scores suck and my feelings started to get hurt that's okay because now I'm the one hurting feelings and breaking hearts alright so the fire strike extreme score was a twelve thousand two hundred and fifty one now I think that that could be improved a little bit with some more tweaking and some more card tuning no it's a joke guys I don't I don't do that seriously this is a pop blood vessel this is not cannabis stop it now when it comes to these scores I am running my cards at a conservative thirteen hundred megahertz in a lobby you're like what do you mean conservative that's huge the base clock is nine sixty seven that's a 343 F make a Hertz overclocked mathur's math is gooder yeah remember guys I'm on reference cards I'm not on for the winds or classifieds or g'wan snipers or any of that crap I'm on a reference card which could blow up at any minute in fact you guys could even get a ball of fire behind me at some point in this video a two of my cards are capable of fourteen hundred megahertz and one of them craps on its face at thirteen hundred and twenty all the way up to 1.3 two volts yeah I don't want to push it any farther than that so I just went ahead and tone back the two good cards to a little bit below the crappy card and so here we are we're just sitting at three cards at 1300 megahertz now 3dmark 11 it's an old benchmark but it's fun to revisit some of these old benchmarks because I remember benchmarking on it back with my GTX 580 when it was new and was like yeah I'm getting seven thousand points whoo I was all excited back then seven thousand points was pretty damn good for 2011 well today on my 3-way GTX 780 s overclocked in water cooled 32 thousand six hundred and twenty-one come on down that's the new score that that's I'm sorry but that's just six that's just sex - look I don't know why computer stuff can can be arousing but I got that was a little awkward all right is going to talk about Unigine heaven benchmark another synthetic benchmark I like to use it because it gives me good apples to apples comparisons on how some of my clocks and stuff are working and how I write my own BIOS I actually wrote my own BIOS for these cards and so I've been testing that out and synthetics give me a good direct comparison of how results are working I can't control multiplayer situations and games like Battlefield so synthetics do have a purpose guys now my engine Haven heaven whatever benchmark is 4037 max FPS 316 average FPS 160 point 3 all right so when it comes to the gaming titles what I went ahead and did here was I ran them in 1080p with all sliders maxed as far as everything could go things like motion blur and anti-aliasing and anticipate filtering all of that stuff and it's entropic whatever i maxed as much of that crap out as i could for my 1080p test and then my 57 60 by 1080 surround test I went ahead and pushed everything as far as I could to the right and disabled anti-aliasing the reason why I do that is I am on three gigabyte cards not the six gigabyte 780 s therefore I am running out of VRAM pretty damn fast at that resolution now when it comes to battlefield 4 I was actually getting in 1080p 160 frames per second average and that map was a 64 player full operation Locker conquest tons of explosions you guys know what I'm talking about if you play battlefield Locker is just like an explosive wet dream yeah that's a hundred and sixty frames per second average now but top-end was peaking at 200 because that's as far as the game can handle and the low-end never dipped below 90 frames per second he bit me that's awesome I'm sorry 144 Hertz monitors come in handy with those kinds of frames now speaking of 57 60 by 1080 as I meant and anti-aliasing turned off and aliasing post fxaa was on by the way but that's free performance it doesn't actually hit your graphics card in any way was getting a 103 frames per second average on three gigabyte cards that's actually pretty good now I can play at that resolution we were maxing out at about 184 frames per second and the average was a pretty playable at 103 I think you'd agree with me even though my monitors were capable of much more 103 is no slouch alright it's time to move on over to the ridiculous benchmarks here no Metro 33 the title is not perfectly optimized it has its problems but I went ahead and used it because I do know it is somewhat demanding now in 1080p we were getting an average frame rate of 121 frames per second in the benchmark with a max frame rate of 291 and a minimum frame rate of 13 and the 13 happened in the frame number 3 so once again it was loading the benchmark so it kind of stuttered and that's where the low FPS comes from 121 average 291 max holy now when we move over to 57 60 by 1080 it's a little bit different story you can tell Metro 33 is not very well optimized for threeways graphics cards in fact the average frame rate dropped all the way down to 50 with the max frame rate still sitting at 228 there was a lot of stuttering and it just seemed like the game didn't really know what to do with the graphics cards considering their usage was sitting at about 50 percent so the game wasn't calling for the performance therefore the cards were like hmm what you want bro we're gonna do something or what so yeah a three way optimization on Metro 33 seems to be well shite now last but not least everyone's video game fantasy Laura Croft with Tomb Raider minimum frames per second 280 max frames per second 461 average frame rate 381 frames Tomb Raider scales with 3-way and that's amazing considering it's an AMD title that anyway moving on to the 57 60 by 1080 test we had a minimum of 116 an average of 134 and a max of 148 pretty good scaling if you ask me now when it comes to temperatures the system is two separate loops and the 50 are the five sixty millimeter rad in the bottom it's a 45 millimeter thick rad by alpha cool and it is housing all three graphics cards by itself and they will top out at about 55 degrees Celsius now the temperatures went up dramatically with the third card being introduced in the loop I mean with two cards I used to sit right around 44 degrees Celsius and I was okay with that but in the summertime like right now it's pretty warm in here and maybe one day from October but it's pretty damn hot still where I live and so the temperatures do start to climb now I was thinking about putting a third radiator in here adding a 360 rad to the front of the case just two more get more dissipation of that heat there may or may not be add some changes to come into this system in the future here when it comes to more efficient methods of graphics if you know what I'm saying you're just gonna have to wait to find out what that means as always guys I hope you've appreciated and enjoyed this video if you have you know what you can do you know what buttons you can push to tell me you liked it and you also know where you can put this video if you hated it a feeling it will fit right in there anyway guys I'm gonna go ahead and get the heck on out of here feel free to flame me for the system if you want it is by far nuts and crazy stupid and I've never owned a system like this and it's kind of hard to believe I built it anyway guys time to get out of here follow on that their Twitter let me know what titles you guys would like me to start including in these future graphics card reviews and as always I will see you in my next crappy video yeah it is over there
